The Noun Project

Icon lovers rejoice, the Noun Project, which is easily searchable and visually pleasing, is a virtual repository for icons of all kinds - over 100,000 of them and counting. A web-based service, it was founded in Los Angeles in 2010 with $14,000 in Kickstarter donations and a dream to "simplify communication, across borders and around the world." Looking for the perfect representation of a tree? Browse the 2,098 possible options. Do you need a phone booth image? There are 4,441 phone booth icons from which you may choose. Icons are downloadable with a free membership, as long as you credit the creator. Readers who would like to waive the attribution requirement may pay $10 per month. Downloads are easy: simply select the desired icon and choose either PNG or SVG file. The Noun Project will do the rest.
